(I don't know if anyone has posted Vpn on trickbd before me. I'm 
sorry if anyone did )
We are all somewhat familiar with the term VPN. However, we all know this name, but very few of us know about it.
Today we will briefly discuss what VPN is, what it does and why VPN is needed.
What is a VPN?
The full form of VPN is Virtual Private Network.
Simply put, a VPN is a fictitious 'tunnel / channel' through which information can be exchanged securely / secretly.
This 'tunnel / channel' does not exist in reality, it is basically a fictional / virtual private network through which information can be exchanged securely on the Internet.
The Internet is a place of open information exchange. Suppose you are playing football in an open field, where many others like you are playing, your ball may go in the middle of their game and their ball may come in the middle of your game, so that anyone can kick that ball. Again, those who play with the entire field, no one else can get in the middle of the game. In the same way, since the Internet is a public network, that is, everyone in the world is connected, there is a risk that the privacy of information will be compromised when it comes to direct information exchange, meaning that anyone can see your information.
To avoid this security risk, VPN is a way to connect to a private / confidential / fictional network to exchange your personal or private information using the Internet. This method creates an imaginary tunnel on the Internet to connect users and private networks.
Now let's see how it works.
When a computer, laptop or mobile is connected to a VPN, the device connects to the VPN server and creates a virtual network that is only for your device. This is why it is called a virtual private network. All your internet traffic i.e. browsing, downloads, server connections will all become VPN connected server. In this case VPN is able to do such a thing that you will feel the Internet from Bangladesh, you are in the country of VPN connected server. By doing this, you can go to the public WiFi zone and keep your browsing safe, as well as you can use services like Hulu, Spotify sitting in the country.
Because when you are VPN connected, your computer will go through any website with encrypted VPN connection. In this case VPN acts as a secure connection between your computer and the website you will connect with. So with hidden VPN easy to use blocked website and service by hiding geo location.
Classification of VPN:
TP PPTP VPN,
→ Site to Site VPN,
→ L2TP VPN,
Remote Access VPN,
Se IPsec, SSL,
→ MPLS VPN,
→ Hybrid the VPN
What are the benefits of VPN / Why VPN is needed?
1. The purpose of using a VPN is to allow you to securely exchange your information.
2. No one will be able to track your location using VPN.
3. You can hide the IP address (Internet Protocol address). In other words, the chances of getting caught by hackers are very low.
4. You will get full speed net from your internet service provider IPS.
5. With VPN you can visit blocked sites in ISP / IIG / Country. For example, if Facebook is blocked in our country, you can still access Facebook using a VPN.
. VPN can also be used for many official purposes. Doing a lot of important work with VPN can protect against hacker attacks. For example, if you are working on a banking server from home, it is very important to use a VPN, otherwise hackers can take information from your server.
How to use VPN and which VPN is better?
Currently there is no shortage of free VPN software and to get most of the VPN services you have to open an account on those VPN websites. After that you have to download and install the registered software. Again, some VPNs like Microsoft Web Store do not need to open an account in Touch VPN. All you have to do is install and connect the app from the App Store.
However, this free VPN software does not have servers in all countries. Also some VPNs may force you to use paid services after using a certain amount of bandwidth.
The advantage of premium VPNs is that their connection process is more secure and in this case paid VPNs are able to give you maximum amount of internet security.
In addition, paid VPNs can be connected to servers in almost all countries and premium VPNs are less likely to lose data.
